What Is Oxygenated Fuel?
What is oxygenated fuel? Oxygenated fuel contains oxygen as part of its chemical makeup. The purpose of fuel oxygenation is often to reduce carbon monoxide levels created while the fuel burns. Usually oxygenates come in the form of gasoline additives, such as alcohol.
Some boaters are concerned with the possibility than an oxygenated fuel can harm their motor and interfere with the performance of their outboard motor oil. Outboard motors can generally tolerate up to 10% alcohol content in fuels, which is the maximum amount allowed by the United States.
